multiple operating systems (parallels and proxmox)

yes, you can run parallels in Big Sur. It will run on apples new M1 sillicon - BUT, as of yet, nobody has made any VM (that I’m aware of) that will run x86 code (eg high sierra, etc) on the M1 chip.
so the advice is, if using big sur, then this applies to parallels still running on Intel platform.
You can run all the VM’s that I’ve created/listed on Big Sur. Most of our team have migrated there and use parallels on a daily basis.
The part that apple makes hard is making VM’s for older operating systems. It is still possible to find instructions and download Yosemite and above (from apple) to make it run in a Parallels VM in big sur. You can still find ISO disk images for windows XP and up to get older operating systems into parallels that are no longer supported by microsoft.
Since we’ve been using parallels for many years, I started making Virtual Machine images of the current operating system and saving them on our servers. wo when on Sierra, I made a sierra VM. then when we upgraded to High Sierra, I made a High Sierra VM. etc etc.
and now I have VM’s for most of my ancient operating systems. and I can use thing like a Big Sur VM on Catalina or Catalina VM on Big Sur.
so. yes, you can run El Capitan in a VM in high sierra…. or win 2000 in a VM in high sierra. but only on the Intel Mac.
this has allowed me, for example, to run Omnis 5 and 7 on older XP virtual machines or even on my win 2000 virtual machines (which we have done recently to go look at some older business logic). About the only thing I can’t run any mode is my Omnis 3 version of product … because I can’t find that OSX puma or cheetah virtual machine that will let me still run omnis 3.
all of which says .. it is worth
1) having parallels (or a virtual machine of your choice)
2) making virtual machines of operating systems you have used with each new mac or windows upgrade
3) hanging on to the last Mac Intel machine before you go M1.
and then you can run anything you've made in the past.
hope that helps.
also, because we use Parallels , we are at the place where it costs $49.99 to update a version and sometimes we wait till its on special for $39.99. We chose to skip every other version of parallels, so that means, in effect, we pay about $20 per year USD for a perpetual licence per machine. We have it on 4 machines, each which upgrades at different years, one of which is a common machine.
thats been what we have done. works for us, mileage may vary.
What about Proxmox??
there are other tools. We use the free version of a server operating system called proxmox on our cloud servers to handle multiple VM’s for windows and linux. Google serach tells you how to set up OSX virtual machines on proxmox.
so, if you have linux servers …. proxmox is a great tool to use for larger data centres. then people can sign on remotely to these apple’ vm's

>> and you can run the virtual machines in two modes. One is normal mode, where it looks like you are running a windows VM in its own windowl, or coherence mode… which makes the windows MDI interface go away and you just see ‘windows’ windows within your mac environment. its rather clever — so whiel the indow looks like another operating system, it is no longer in a container. Kind of seamless.
